Application filed February 10, 1906. Serial No. 300,537-

To aZZ whom, it may concern:

Be it known that I, GEORGE WILLIAM h/IORETON, a citizen of the UnitedStates, re siding at Wilmington, in the county of Newcastle and State ofDelaware, have invented certain new and useful Improvements in DrivingMechanism; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to mechanism for driving planing-machines andother similar reciprocating tools; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed, whereby the machine is driven forward at one speed and inthe reverse direction at an increased speed.

In the drawings, Figure 1 is a front view of parts of a reciprocatingplaning-machine provided with driving mechanism according to thisinvention. Fig. 2 is a side view of portions of the machine and thedriving mechanism.

A is the frame of the reciprocating planing-machine.

B is the table for carrying the work, which is slidable longitudinallyon the bed B.

C is the girth or cross-piece at the top part of the frame. D is themachine-shaft which is ournaled in the bed under the table and the endportions of which project at each side of the machine.

E is a belt-pulley secured on one end portion of the shaft D for drivingit in a forward direction, and E is a similar belt-pulley secured on theother end portion of the shaft D for driving it in the reversedirection.

F is a motor of any approved construction which is secured to thecross-piece C and provided with a main driving-shaft 6. This shaft 6 isjournaled in suitable bearings f and is preferably formed in sectionssecured together by a coupling 6. The machine-shaft D can also be formedin sections secured together by any approved coupling in a similarmanner.

The table B is driven by the machineshaft by any approved drivingdevices, such as toothed wheels and pinions and a toothed rack arrangedunder the middle part of the table. These parts are not fully shown in[the drawings, as they do not differ materially from those ordinarilyused. It is immaterial whether the machine-shaft D is formed of a singlepiece or in sections, proand provided the machine is provided with twoindependent driving-pulleys arranged one on each side of its frame.

G is a single counter-shaft which is ournaled in bearings g at the u perpart of the frame. A toothed pinion is secured on the shaft 6 and gearsinto a toothed wheel g on the shaft G, so that the said shaft G isdriven at a slower speed than the shaft 6 and in the reverse direction.

His a belt-pulley secured on the countershaft G, and h is a belt whichpasses over the pulleys H and E and drives the machine in a forwarddirection.

H is a belt-pulley, preferably larger in diameter than the pulley H andsecured on the shaft e. A belt h passes around the pulleys H and E anddrives the machine in the reverse direction.

In carrying out this invention any approved means for revolving the maindriving-shaft e can be used instead of the motor shown, and any approvedwheels and flexible driving devices can be used for connecting theshafts instead of the pulleys and belts shown.

The machine is driven by pressing one or the other of its driving-beltsinto driving contact with their respective pulleys on the machine-shaft.

Similar pressing mechanisms are provided at each side of the machine,and the description will therefore be confined to the pressing mechanismon one side of the machine.

I is a presser-lever provided with a pin i, by which it is pivot-ed to abracket I, secured to the side of the machine-frame.

J is a presser-pulley which is mounted on a shaft j, carried by thelower end portion of the lever I.

A stop J is provided for limiting the forward motion of the lever I, andthis stop preferably consists of an adjustable screw which engages witha lug j on the bracket I.

K is an air-cylinder secured to the side of the machine and providedwith a piston and a piston-rod K, which is connected with the upper endportion of the lever I by a link 7c and suitable pivot-pins. Theair-cylinder is vided its sections are operativelyconnected provided;with a valve L of any approved construction and pipes for distributingcompressed air to the ends of the cylinder, and therebyoperating theresser-lever.

M is the valve-lever which is secured on a shaft m and operativelyconnected with the valve L. The shaft m is journaled in the bed andpasses through it, and a similarvalve-lever is secured on its endportion at the other side of the machine. The respective valves andtheir connections are so arranged that when one resser-lever is moved inone direction the other presser-lever is moved in the reverse direction.In this manner it is impossible to press both belts on their pulleyssimultaneously. The air-valves are operated automatically by tappetmechanism.

Nre resents tappets or dogs carried by the table andadjustable in theusual manner.

' N is the 'tappet-lever, which is pivoted to the bed, and n is a rodwhich is pivotally connected to the tappet-lever N and the valvelever Mby pins n. The tappet mechanism may 'be'of any approved constructionused on machines of this class.

P represents standards which are secured to the brackets I and whichsupport the outer end portions of the main shaft and countershaft.

When the motor is in action, the main driving-shaft and thecounter-shaft are revolved continuously, and the belts connected withthem are driven in opposite directions. When the presser-pulley isoperated to tighten the belt h upon the pulley E, the table of themachine is driven in a forward direction and the work secured to it issubjected to the action of the planing-tools. WVhen the tappet mechanismreverses the air-valves, the pulley E is released from the belt h, andthe belt h is pressed into driving contact with its pulley E, so thatthe table is moved in the reverse direction and at an increased speed.

What I claim is '1. The combination, with a machine of the characterdescribed provided with two longitudinally-arrahged side frames, acrosspiece secured between the upper parts of the said side frames, anda reciprocatory worktable arranged between the said side frames; of amain shaft provided with means for revolving it, a counter-shaft, andtoothed wheels connecting the adjacent end por- "tions of the saidshafts, said shafts being arranged above the said cross-piece and sideframes with their opposite end portions projecting beyond the planes ofthe said side frames; driving-pulleys secured on the prO- jecting ndportions of the said shafts and revolving in opposite directions, twopulleys for driving the said work-table forward and backwardrespectively, said pulleys being ar ranged longitudinally of the saidside frames and at their lower parts, belts connecting the said pulleyswith the said driving-wheels respectively, and means for tightening andreleasing the said belts alternately.

2. The combination, with two side frames, and a cross-piece extendingbetween their upper parts; of a motor provided with a shaft andsupported by the said cross-piece, a counter-shaft also supported by thesaid cross-piece, toothed wheels connecting the adjacent end portions ofthe said shafts and constraining them to revolve in opposite directions,the opposite end portions of the said shafts being arranged to rojectbeyond the planes of the said side ames, pulleys arranged on theopposite end portions of the said shafts outside of the said sideframes,

outside of the said side frames-at the lower parts thereof, beltsconnecting the said pulleys with the said driving-pulleys respectively,and means for tightening and releas ing the said belts alternately.

In testimony whereof I have affixed my signature in the presence of twowitnesses.

GEORGE WILLIAM MORETON.
